dfb94ccec1 Add a global type map to the monitor and rename slotList to globalSlots. 2008-08-18 21:08:35 -07:00

76380c598b Add a final js_ReconstructStackDepth assert after setting fp->regs->sp in js_ExecuteTree's bail-out epilog. 2008-08-18 19:26:47 -07:00
Brendan Eich
87a6e416ef 1. Fix json2.js (it crashes later, another bug) to restore a non-empty stack for a call with missing args after a nested bail-out. This involves changing js_SynthesizeFrame to return the number of stack slots it reconstructed that map to native slots. It also means not counting the missing args in the spdist uint16 pushed onto the state.rp stack (this was the root of all over-counting evil, for this bug). 
2. Use if (C) { do {...} while (C); } instead of if (C) { while (C) {...} } and other style fixage.

202a9de38b Doh. Deep bailots are pretty rare and js_SynthesizeFrame already uses the fairly slow js_ReconstructStackDepth helper internally, so anotherone to avoid counting stack slots via spbase can't hurt. 2008-08-18 10:04:03 -07:00

9f71dd226f Extend the globalTypeMap import(), not in the caller, since we missed extending it in case of re-reading registers after a tree call. 2008-08-17 11:38:49 -07:00

f08e18fc14 If RecordTree is triggered, create a new peer fragment (or recycle and unused one) if we already have a tree for this location. 2008-08-17 00:49:59 -07:00
Andreas Gal
2d983bcee2 Try to execute the tree first, and if that fails worry about counting and triggering compilation. This speeds up trace activiation by a tiny bit, but makes code that we can't trace a little bit slower. We use a micro optimization to bypass the call to js_ExecuteTree when its clear that it wouldn't find a tree to executed to reduce this overhead. This change is necessary for multiple trees per bytecode location. 2008-08-17 00:30:36 -07:00
Andreas Gal
ef8a6041cc Give root fragments a treeInfo decorator only if the trace was successfully compiled. Otherwise just keep a reference in the recorder and delete it when the recorder is destroyed. Review welcome. The involved state machine is a bit complex. Added lots of asserts as safety net. 2008-08-16 23:43:49 -07:00

26fc76213a Only capture the shape of the global object in a tree once that tree tries to access a global, and only check the stored global shape in trees against the current global shape if the tree actually uses globals (which also doesn't trash trees when global variables are added if that tree doesn't actually use globals.) This is approx. a 1% win for sunspider. 2008-08-16 21:05:03 -07:00
Andreas Gal
efd76e5daf Change interface of js_ExecuteTree to indicate which of the peer fragments it really executed (since we soon will have more than one tree that could be activated for that particular bytecode location). 2008-08-16 15:45:48 -07:00

7b954b5cd7 Add the concept of peer fragments to nanojit. Each loop fragment can have a number of peer fragments, which we can use to have several different specialized variants of a loop (i.e. for different types). The makefile doesn't pick up the change to Fragmento.h, so make sure you clobber by hand or you will end up wasting an hour of your life in gdb (like me.) 2008-08-15 20:15:47 -07:00

10a24ff80c Don't allow inner trees to lazily pick up any globals since we currently can't handle that. We already ensure that we don't inline trees that have globals. This patch merely makes sure they don't get some additional globals on the fly. 2008-08-15 18:00:22 -07:00

dea1843401 Similarly to attaching new branches to a side exit, we might end up with a partial type map when exiting from a trace during tree execution, so make sure to merge in missing types from the tree's entry map in this case as well. 2008-08-15 17:11:57 -07:00

91a71447a9 Change sp_adj in guards to always reflect the current stack depth, so if we enter a trace/loop with something on the stack, sp_adj will reflect always at least that minimum amount. InterpState->sp now always runs in parallel with regs->sp of the current frame. This breaks nesting badly. I really need help with the stack layout logic. 2008-08-15 10:09:36 -07:00
